FERROTYPING,POLISHIN G, AND DRYING APPARATUS.

Application filed September 7, 1922. Serial No. 586,767.

To all whom it may concern:

Be it known that I, A VIN LOUIS MAYER, a citizen of the United States, and resident of New York, in the county and State of New York, have invented certain new and useful Improvements .in Ferrotyping, Polishing, and Drying Apparatus, of which the following is a specification.

It has been customary in the preparation of ferro-typed prints to use a pluralit of rectangular plates which are polishe by hand from time to time. The ferro-type tin plates are washed, then polished and the photographs placed upon them. The water is then squeegeed through a hand operated roller and the photographs are allowed to dry upon the ferro-type tin plates by being placed upon racks to be air dried.

All of these operations are manual and consequently varying results are produced because of the impossibility-of performing each operation exactly alike at all times. Moreover considerable time is required to perform all of these operations.

My invention is designed to overcome these objections, and perform the steps of squeegeeing, polishing, drying, and the like in their proper sequence automatically and thereby produce a uniformity of result obtainable in no other way.

I provide a rotary internally heated drum around which passes a thin metal belt upon which the photographs are placed, and a canvas belt, the photographs being between the two belts and the canvas belt being next to the heating drum. Means are also providedfor polishing the metal belt and pass ing it between two squeegee rollers. The

device may be driven by a motor and such speed selected as will thoroughly dry the ferro-typed prints in their passagethrough the device. p v

Various other objects will be evident from the following detailed description and the appended claims.

Inthe drawingsz'. Figure 1 is a side elevation, somewhat diagrammatic in character. Figure 2 is a vertical cross section on the line 22 of Figure 1.

Figure is a fragmentary detail of the polishing rollers showing them removed from contact with the belt.

Figure 4 is a sectionon the line 4 -4-01? Figure 3.

Figure 5 is a detached detail view of the shifting devices.

Figure 6 is a diagrammatic view showing a modification employing a plurality of heated drums.

A frame is formed of two pairs of upright standards 1 and 2, which are connected at the sides by pairs of bars 3, a and 5. In the bars 4 is mounted a gas pipe/6 which may be perforated to serve as a burner, and is connected in any desired mannerto a source of gas supply. This pipe serves as an axle about-which revolves a drum 7 having a series of vent holes 8 in its sides and near the center a large hole 9 for observation purposes and to enable the gas burner to be readily lighted. This drum is made up of a corrugated metal surface indicated at 10.

A. driving drum 11 has its axle mounted in the uprights 2 and is provided at one end with a worm gear 12 which meshes with a ,worm' 13 on the upper end of a rod 14 mounted in bearings 15 on the side bartand a retainer 16 on the side bar 3. At its lower end this rod has a pulley 17 around which passes a belt 18 which also passes around a pulley on a motor 19. In this manner the operation of the motor drives the drum 11 and produces the movements of the bel s about to be described.

An idler pulley 20 has its axle ends mounted in blocks 21 sliding in slots 22 in one end of the side bars 5, and these blocks are adjusted in position by screws 23 in a well known manner. A belt 24 of canvas or similar soft material passes around'thi-s idler 20. Starting for example at the point an the course of this endlessbelt may be traced as follows. It passes around the idler, downward and next to the heated drum 7, up to a point about in line with the side bar 4 when it lea ves the heated drum and passes over theidler 25 mounted in the sidebars 5. After leaving this idler it again contacts with the heated drum and finally passes under the driving drum 11 and up to the ,point x. p An idler 26 is carried. by the extended ends of the side bars 4 and is adjusted similarly to the idler 20. A pair-of pivoted arms 27 carry a squeegee roller 28" and a cooperating for carrying off the Water.

A second belt 32 made of relatively hard metal thin enough to bend readily may be traced as follows starting from the point '0. It passes up and over the idler 26, between the squeegee rollers 28 and 29 which are drawn towards each other by a spring, 33, down under the heated drum 7 contacting directly with the canvas belt 24, up over the idler 25, from thence to the heated drum, under and around the driving drum 11, up over an idler 34 mounted in the upper ends of the standards 1,. down over a small idler 35 similarly supported after which it contacts with a waxing device36, under a larger drum 3? and upwards to the starting point o.

The pulley 7 5 is loosely mounted on shaft of drum 3'] and is driven by a belt 38 from the motor 19, and through a belt 39 it drives a pair of polishing or butting rollers 41 which are mounted to press the belt against the large drum 37. These rollers are carried by a pair of arms pivoted to the cross bar 3 andat their lower ends are attached to a pair of sliding blocks 42 on a rod 43 supported in suitable bearings 44. Each block 42 has'an angular slot 45 therein which are arranged in opposite directions. Pins 46 on the shaft 43 enter these slots, so that a rotation of the shaft will cam the blocks in opposite directions and thereby move the arms 40 about their pivot points to carry the rollers 41 out of contact with the drum 37, or from the position shown in Figure 1 to that shown in Figure 3. Springs 47 interposed between the blocks 42 and the bearings 44 tend to hold the blocks at their inmost position and keep the rollers 41 in operative relation to the belt and drum. A pedal 48 is attached to one shaft 43 for the purpose of rocking the same and may be connected to a similar shaft 43 at the opposite side of the device by a link49 (see Figure 4),

A pair of toggle links 50 are pivoted at 51 to the arms 40 near their lower ends and at their upper end carry an idler roller 52 over which passes the belt 39. When the pedal 48 is operated to move the rollers 41 out of operative position, these links allow the idler roller to drop and slacken the belt so that the rollers 41 need not be driven when not in use.

' This mechanism is omitted from Figure 3 for the sake of clearness.

Carried by the side bars 5..at one end is a tray 53 which receives the prints as they come from the metal belt 32.

Figure 6 shows in diagrammatic form an arrangement in which, a second heating drum '7 maybe employed in addition to the first drum. An additional idler 54 is provided for the canvas belt and an additional idler 55 forthe metal belt. The other parts are similar to those shown in the first modification. It will be noted that whereas the can- 'vas belt is nextto the first heating drum 7, the relation is reversed when the belts pass.

e -eases the idler and this permits the escape of themoisture of evaporation created by the heated drum. The periphery of the drum is corrugated and this forms air pockets which also assist in permitting the escape of moisture formed by the heating operation.

Tnoperation the burner is lighted and the drum permitted to rotate until the desired temperature is reached which will thereafter remain substantially uniform. The metal belt passes over the idler 26 in polished condition and the prints are laid thereon at about the point 2': They are then passed between the squeegee rollers 28 and 29 where the most of the moisture is pressed out, the water dripping into the pan 30. As the drum 7 is approached the canvas belt comesinto engagement with the metal belt, and the prints are between the two belts, the canvas belt engaging the drum. The belts travel as indicated by the direction of the arrows around the drum, over the idler 25, into engagement with the drum once more, and into engagement with thedriving drum 11. Moving upward there from they separate, the canvas belt going around the'adjustable idler 20 while the metal belt continues upward toward the idler 34. Just before the belt reaches this idler the prints are in condition to be de' posited in the tray The belt then turns downwardly passing over the small idler 35, past the waxing device 36, and between the large drum 37 and the polishing or,

butting rollers 41 where it is given a high polish and is again ready for the application of prints. From these rollers it moves upward to the idler and the operation is repeated. a

For the purpose of obtaining the best results from a machine of this description, the metal belt should be highly polished and the polish maintained. However, a demand for less exact finish of the prints can be met by an abrasion of the surface of the rollers 28 and 29 which will afford a'linen or --matted effect to the surface of the paper. Obviously under such conditions the polishing rolls will be thrownout of operation and if desired, means may be provided for holding them out of operative position.

lit is obvious that I have provided means for carryingout the operation in a contin= uous manner and with substantially "uniform quality of the work. The .speed of travel of the belts will be selected in such manner as to afford the proper drying in their movement about the drum. \Vhile' a gas heated drum has been described, obviously the invention is not limited thereto.

Many details can be changed without departing from the spirit of the invention. The machine may be made of any desired size according to the character of the work to be performed. The canvas belt may be made of any suit-able cloth material. In general it may be stated that the invention is limited only by the scope of the appended claims.
